The one way bearing wasn't holding pressure enough for a smooth/fast enough rotation.
As every time it came up to TDC on a compression stroke it would slip(common noise for one way bearings going out is "banging")
Because of it slipping, it wasn't be able to spin the motor at a fast enough rpm to register to the pcm to fire the injectors.
I originally thought it was the one way bearing due to the fact that when turning over the motor it would "bang"
But, everything said that the coils get there reading from the same place as the injectors.
I always had spark at cranking.
So, that's why I started to lean towards and electrical issue.
But, after I had ohmd components out and what not, I went back to what I originally thought it was.....the one bearing.
The 35 tooth encoder ring with a missing tooth is built onto the flywheel. The CPS is mounted above the encoder ring. During rotation, an AC pulse is created with each passing tooth on the ring. The ECU calculates engine speed from the time interval between the consecutive pulses.
The missing tooth on the encoder ring creates an "interrupt" input signal, corresponding to a specific crankshaft position. This signal serves as a reference for the control of ignition timing by the ECU.
Synchronization of the CPS and crankshaft position takes place in the first 2 revolutions each time the engine is started.
If the sensor fails or becomes disconnected for any reason the engine will stop running.
Super newbie owner here. We bought a used 2013 Ranger Crew 800 EFI. After a couple weeks it just wouldn’t start. I press the brake pedal, turn the key, and the electronics on the speedometer light up, but nothing happens.
We had the battery and solenoid checked, and they’re good. Where do we go...
I have a 2013 Polaris Ranger 900XP. I recently rebuilt the front differential about 6 months ago because it was locking up in reverse. Everything is new inside except ring and pinion. When connected to the driveshaft, wheels will lock up in reverse. When disconnected from drive shaft the front...
Watched several videos on YT of folks changing torn tie rod boots. They all had the tie rod on a bench. Looks to me like you could change the boot without removing the tie rod from the gear box assembly. Possible? Machine info is in the signature. Thanks for your replies.
My Ranger has suddenly lost power and will not accelerate. Acts like limp mode kind of. No check engine light. When depress throttle completely it does not accelerate. I am thinking pedal sensor but I am not real sure.
